Great sound paired with GX model TVs

TorresFam 10/23/2020

I have had many soundbars but this is definitely the nicest I have ever owned. This sound bar looks amazing and pairs perfectly with our LG GX TV. We have a 55 GX model TV and didnt notice this sound bar is 65 so it doesnt match up exactly but it still gets the job done and looks ok. The soundbar mounts perfectly below our LG GX model TV and is much thinner then expected which made me wonder when it came to sound. The subwoofer sits perfectly on our floor to make it feel like the floor is shaking when its on which is nice and it was pretty easy to set up but I did notice there arent a lot of sound options which surprised me. We like the movie option the most since the sound with the subwoofer gives you a movie like experience. I like the thin design of the sound bar and how easy it was to install on our wall. The remote took some time getting used to but is pretty basic. Its better when you can pair it to your TV/cable remote. This Soundbar was specifically made for OLED GX Gallery model TVs and since enhances the sound. The sound bar is Bluetooth enabled and can be paired with compatible devices and Dolby Atmos allows you to hear every note every sound and every word in stunning clarity. I like how their arent a lot of wires involved other then the plug and one HDMI wire that goes from the TV to the sound bar you cant really see. The sound bar combines Meridian sound technology Dolby Atmos DTS-X and HiRes Audio up to 24bit 192KHz for highly-realistic audio performance making any content-viewing or listening experience far more immersive. The soundbar also comes with the Google Assistant built-in and offers the convenience of AI smart connectivity and voice recognition without the need for an extra device. I am really enjoying this sound bar but dont think Id have the need to purchase it if I didnt have a GX model TV since I thinks it works best and is more compatible.

Amazing Sound

LoriLeal1 10/23/2020

The LG High Res Audio Sound Bar GX with Dolby Atmos has completely exceeded my expectations. I honestly didnt think a soundbar was something I really needed but I was curious to give one a try. Im so glad I went with this one because its perfect We have a lot of movie nights at home especially now that were in a pandemic and I just didnt realize what we were missing before the LG sound bar. Its fantastic and I highly recommend this brand. Very pleased

LG GX Soundbar

Rotciv17 10/23/2020

I received my LG GX 3.1 ch soundbar and it arrived and in a big and flawless packaging. The box itself shows that it is a top notch product. The soundbar and subwoofer came nicely packaged and protected. As I opened it up I got to see how sleek the design is. The pictures do not do it justice. This is a one of kind product. Mounting was one of the easiest setups with very easy to follow instructions. It fits flush against the wall like a picture frame. It really is a thing of beauty. LG really hit tit out the park with this one. Connecting the soundbar was as easy as 123. I used the hdmi arc port and the soundbar just automatically connected. After that I plugged the subwoofer in and in a matter of seconds it connected wirelessly to the soundbar. No need to press any buttons. Its literally plug and play. Ready to go in seconds. I switched to bluetooth connectivity and It was also up and running without any issues. I decided to play a movie with great sound effects to test the limits of the GX soundbar. I chose Transformers. The sound was so immersive it felt like I was in the movie. You are able to hear every distinct sound coming from the movie. The subwoofer really puts this soundbar over the top. It sounds so clear with great bass. The combination of this soundbar and subwoofer really fills the room like a movie theater. Next I tested the soundbar by playing the new avengers video game on ps4. You literally feel every move the character is doing on screen coming from the soundbar and subwoofer. From a wall breaking or hulk doing his signature smash. You can hear every distinct sound on anything you play. While playing Spotify it literally sounds like you are having a concert in your house. In conclusion this is by far the best soundbar on the market. From a flawless sleek design to crisp and clear sound. I was blown away by the sound the GX can push from such a minimalistic design. I would highly recommend this product to anyone. Pair this up with the GX oled tv and you will have the best dynamic duo on the market. If you want the best sound and picture quality on the market this is the way go. I Really do not have any complaints I am beyond happy with this product.

No option to match 55 GX TV

MisUszatek 10/7/2020

It will only look matched with 65 TV. With 77 tv will still look decent but with 55 looks hideous.

Great sound bar and subwoofer

rob165 10/2/2020

I received my LG GX 3.1 channel high res sound bar is awesome. It was very easy to set up and connect to my tv. I used the optical cable because I tried to use a hdmi cable but it wouldnt work. After reading the book it said my tv may not be compatible with the newer technology in it. I tried the optical cable and it works perfect. The sound is amazing and it gets really loud. The bass from the subwoofer is good too. My while 2100 square foot home shakes from it The sound bar connected to my phone easily once I turned the Bluetooth on my phone on. It sounded great. The remote isnt that bad. It is small and has all the necessary buttons on it. It was easy to adjust the source or the bass and treble.
